GrowthBook is more than just an experimentation platform—it's a philosophy.
We believe in empowering your team to experiment boldly and confidently, knowing your data is secure and accessible. Take control of your experimentation journey with GrowthBook.
Our Philosophy
Open source promotes trust. Complete data transparency leads to better product decisions.
Feature Flags are the best way to launch features
A/B testing is the best way to measure impact
Keep your data where it already lives
Data must be trustworthy to guide good decisions
Platform speed is paramount to experiment quality
Incremental experiment costs should be close to $0
Origins
GrowthBook was born when our founders, Jeremy and Graham, hit the limits of costly third-party A/B testing tools.
- They couldn’t use their actual data—the tools required proxy metrics
- They couldn’t reproduce the results they received—data remained trapped in a blackbox
- They couldn’t experiment freely—licensing and usage fees discouraged running enough tests
Coming from backgrounds in education, they knew rapid testing and "failing fast" led to accelerated learning. They envisioned an open platform embracing that iterative mindset.
After building their own in-house solution, they realized most companies lacked the resources to do the same. They launched the open-source GrowthBook experimentation platform in 2021 to empower the broader community.
